Pre-Planned Maintenance for Facilities Management

Our Proactive Approach to Protecting Your Estate

A blocked drain rarely stays a drainage problem for long. Left unmanaged, it becomes an operational disruption, then a compliance risk, then an unplanned line on a budget that was already signed off. For facilities and estates managers running multi-site portfolios, that unpredictability is the real issue, not the blockage itself.

London Drainage Facilities Ltd Pre-Planned Maintenance (PPM) programme replaces that unpredictability with structured, scheduled visits at a fixed, agreed cost. Every visit is planned and every visit is reported, and under an LDF PPM agreement your essential pipework is protected by the LDF Promise: any call-out relating to pipework listed in your service schedule is covered at no additional charge, no quibble.

FAQs About Pre-Planned Maintenance

Why is regular drain maintenance important?

Regular drain maintenance helps prevent blockages, reduces the risk of costly repairs and keeps your drainage system functioning efficiently. Over time, scale, grease and debris build up inside pipes, which can lead to slow drainage, foul odours and potential structural damage. Our routine servicing ensures your drains remain clear and free-flowing, minimising disruptions to your home or business.

Is it worth upgrading from a vented to an unvented cylinder?

For many homeowners, upgrading offers better water pressure, improved energy efficiency, and valuable space-saving benefits. If you’re renovating or modernising your home, an unvented system is often a smart investment.

Can I use an unvented cylinder with any boiler?

Unvented cylinders work well with system or regular boilers, but not with combi boilers, as combi systems don’t require a hot water cylinder. Your installer will help determine the best setup based on your current system and hot water needs.

How much maintenance does an unvented system require?

Unvented cylinders should be serviced annually by a qualified engineer to ensure they remain safe and efficient. Regular maintenance helps prevent issues and extends the lifespan of the system.

Do I need good water pressure to install an unvented cylinder?

Yes, because unvented cylinders rely on mains pressure, it’s important to have a strong and consistent water supply. A qualified installer will assess your pressure levels during the initial survey to ensure suitability.

Are unvented systems safe?

Yes, unvented hot water cylinders are very safe when installed and maintained correctly. They are fitted with multiple safety features such as pressure relief valves, thermostats, and expansion vessels to prevent overpressure and overheating.

What is an unvented hot water cylinder?

An unvented hot water cylinder is a sealed system that connects directly to the mains water supply. It delivers hot water at high pressure without the need for a separate cold water tank in the loft, making it a more modern and space-efficient solution.

How often should drain maintenance be carried out?

The frequency of maintenance depends on factors such as usage levels and the type of property.
